What is the iges file format?

iges is a file format based on NURBS, which can be opened with AutoCad. If not, you can first convert it to DXF in Rhino and then open it.

The Initial Graphics Exchange Specification (IGES: Initial Graphics Exchange Specification) was jointly developed and implemented by the National Bureau of Standards and industry in 1975. The IGES interface (IGI: CATIA IGES Interface) provided by CATIA V5 can help manufacturing companies with multiple CAD/CAM systems coexisting to exchange data through the IGES neutral data format.

This utility supports IGES V5.3 version, and has the name matching management function between IGES element names and CATIA V5 geometric element identifiers, and can handle 3D wire frame elements, surface and shear surface elements, etc. Offset curves, epidermis and epidermis boundaries, conics, and color. After the conversion is completed, an HTML format conversion report is generated at the same time. Designers can perform reliable bidirectional data exchange directly between two completely different systems and can also automatically access IGES files.

IGES——A specification for data exchange between CAD or CAM systems

With the rapid development and popularization of CAD/CAM technology, various companies are actively adopting it CAD/CAM technology. Due to historical reasons and different development purposes, the internal data recording and processing methods of each CAD/CAM software are different, and the languages ​​​​of the development software are not completely consistent. Therefore, CAD/CAM data exchange and sharing is an important issue. . Since the early 1980s, foreign countries have done a lot of research and development of data exchange standards, and many standards have been produced. Such as DXF, IGES, ESP, PDES in the United States, SET in France, VDAIS, VDAFS in Germany, STEP in ISO, etc. These standards have greatly promoted the promotion and application of CAD and CAM technology in various countries.
